مرحبا من فضلك مساعدة ماذا يفتقر هذا الرمز للعمل؟ مطلوب عدم تكرار الحقل في ملف نصي يرجى تعديل الكود

<?php

if(isset($_POST['send'])){
$b1 = $_POST['b1'];
$b2 = $_POST['b2'];


$file = fopen("xm.txt", "a+");

				for($i = 0; $i < count($file); $i++){
					$read = explode("||" ,$file[$i]);
 

    if($read[0] == $b1  ){

        echo 'Duplicate';
 
}
else
{

 

   fwrite($random_file,$b1.'||'.$b2."\r\n");
  fclose($random_file);

 
   }

}

}

?>
